Hey, really cool concept!
The artstyle is super nice, and the overall gameplay bears the seeds (pun intended) for a really pleasant experience.
One thing that bugged me is how the controls and the texts are all player-oriented. for the tank controls you eventually get used to it but it's not super intuitive. The texts, tho, are really hard to read sometimes.
Also, if the cursor followed the mouse (at least in a certain range around the player) it would feel smoother I think.
Other than that, ggwp :D
